Sri Aurobindo describes a possible development of a World-State, somewhat along the lines we see in the way the United States developed with a central Federal government having legislative, executive and judicial powers to overrule and govern the individual states. At the world level, such an executive and legislative authority would initially govern the relations between the various nations which constitute the world body. The initial idea behind the League of Nations and later the United Nations was formulated to try to provide a forum and moderating influence on the relations between nations while the individual autonomy and sovereignty of each nation was preserved. It is obvious that such a solution does not rise to the level of organisation and efficiency, nor have the ability to enforce or direct the actions of individual nations. Thus, the larger global issues find no true solution. Eventually, for such a body to succeed in its goal, it must acquire the ability to regulate, make laws and rules, and enforce them upon the nations, just as the federal authority in the United States has evolved in its relations to the individual constituent states.
Sri Aurobindo describes the steps in this proces: “Our supposition for the moment is that a well-unified World-State with the nations for its provinces would be the final outcome. At first taking up the regulation of international disputes and of economic treaties and relations, the international authority would start as an arbiter and an occasional executive power and change by degrees into a legislative body and a standing executive power. Its legislation would be absolutely necessary in international matters, if fresh convulsions are to be avoided; for it is idle to suppose that any international arrangement, any ordering of the world arrived at after the close of a great war and upheaval could be permanent and definitive. Injustice, inequalities, abnormalities, causes of quarrel or dissatisfaction would remain in the relations of nation with nation, continent with continent which would lead to fresh hostilities and explosions. As these are prevented in the nation-State by the legislative authority which constantly modifies the existing system of things in conformity with new ideas, interests, forces and necessities, so it would have to be in the developing World-State. The legislative power, as it developed, extended, regularised its action, powers and processes, would become more complex and would be bound to interfere at many points and override or substitute its own for the separate national action. That would imply the growth also of its executive power and the development of an international executive organisation. … It would reduce the now free and separate nations first to the position of the States of the American union or the German empire and eventually perhaps to that of geographical provinces or departments of the single nation of mankind.”
